The following review examines
the advantages and disadvantages of several popular
diet plans. Most of the diets are based on
low-carbohydrate approaches. These hotly debated
low-carbohydrate diets were subject of a recent
study in the "Journal of the American Medical
Association" that found more research is needed
on the safety and efficacy of such plans. The
article analyzed hundreds of published studies about
low-carbohydrate plans and found a lack of
scientific evidence for or against the diets.
"It is also important to
note that in most of the studies contained in the
analysis, weight loss occurred when study
participants were on diets for longer periods, and
when they ate fewer calories," according
to a statement by Robert H. Eckel, a physician and
chair of the American Heart Association's Nutrition,
Physical Activity and Metabolism Council.
Keeping that in mind, let's look at a few popular
diets, and go through some of the pros and cons, and
the theory behind their potential effects.
The Atkins Die
(Robert C. Atkins, M.D.)
The Diet Plan Theory:
The Atkins diet is a high-protein, high-fat,
low-carbohydrate plan. The diet allows for
unrestricted amounts of meat, cheese and eggs
while severely restricting carbohydrates,
including sugar, bread, pasta, milk, fruits and
vegetables. Atkins' diet is based on the theory
that eating carbohydrates creates a production of
insulin, a hormone secreted from the pancreas,
leading to increased weight gain and hunger, which
is a true physiologic response. When converting to
this approach, the plan holds that dieters will
experience reduced appetite and their bodies will
use stored fat for energy versus burning glucose
from carbohydrate digestion. Burning fat for
energy will supposedly lead to weight loss.
Disadvantages:
The medical community continues to debate the
potential damaging effects of long-term,
high-protein diets on kidney function, cholesterol
levels, and possible increased risk of heart
disease, osteoporosis and cancer. The Atkins diet
restricts carbohydrates and limits the amounts of
fruits, vegetables, milk and other high-fiber
foods. These foods naturally provide essential
vitamin and minerals to maintain health. Atkins
diet followers may have difficulty maintaining
this diet long term. The problem is taste. The
only way to really satisfy taste without
carbohydrate is by increasing fat. And this is
another concern with the Atkins plan. Weight loss
occurs predominately through a process called
ketosis, and a majority of it
(at least initially)
is fluid loss. There have been no long-term
randomized studies to support the safety of this
diet.
Advantages:
People like eating high amounts of protein foods
that are often restricted on other diets. Those
who have been unsuccessful on other low-fat,
high-carbohydrate diets will often lose weight
with this plan. The diet is easy to follow; no
point system, calorie counting or complicated meal
plans are involved.
A good supplement to take while on the Atkins
diet would be herbal phentermine or dietrine
patches which boosts your energy on your low carb
diet. For those of you that cheat with the we
suggest buying a bottle of dietrine carb blocker.

The Carbohydrate's Addict's
Diet (Richard Heller,
M.D. and Rachael Heller, M.D.)
The Diet Plan Theory:
The Carbohydrates Addict's diet is a
low-carbohydrate eating plan. The diet recommends
eating low-carbohydrate meals and one "reward
meal" daily. The reward meal combines
carbohydrates, protein and vegetables. It must be
eaten within an hour from start to finish. The
Hellers' diet is based on the theory that many
overweight people are carbohydrate addicts; they
suffer from a biological condition caused by a
hormonal imbalance. Excess insulin is produced
after eating carbohydrates, resulting in all-day
food cravings and a willingness in the body to
store fat. The plan holds that converting to this
low-carbohydrate plan reverses such biological
conditions, reducing appetite and body fat
storage. The body will convert to burning fat for
energy versus burning glucose from carbohydrate
digestion. In general, although the finer points
may differ, this can be viewed as a modified
Atkins plan.
Disadvantages:
There are no long-term randomized studies to
support the theory of carbohydrate addiction.
Enjoying carbohydrate foods is not enough for an
addiction diagnosis. Also, there are no long-term
randomized studies to support the safety of this
diet. Eating a low-carbohydrate diet leads to
consuming larger amounts of fat and protein.
Although debated by the medical community,
long-term low-carbohydrate diets are believed to
increase risk for colon cancer and osteoporosis.
High-fat and high-protein diets could cause kidney
function loss, elevate cholesterol levels and
increase risk of heart disease. Following this
diet long term will be a challenge for many.
Advantages:
Weight loss may occur with this diet. It provides
a comprehensive list of foods to consume. It
encourages drinking plenty of water daily. It is
less restrictive than the Atkins' diet. |

The Pritikin Principle
(Created by Nathan
Pritikin, Revised by Robert Pritikin)
The Diet Plan Theory:
The Pritikin diet is a low-fat, high-carbohydrate
eating plan. The focus is to eat vegetables,
fruits and high-fiber grains. Fats should not
exceed 10% of total daily calories. Nathan
Pritikin's diet is based on the theory of eating
low-fat, low-calorie, plant-based foods to promote
weight loss and improve or prevent heart disease.
The revised Pritikin diet includes a "Calorie Density
Solution" - consume low-calorie dense
foods (e.g. apples, brown rice) until full six to
seven times daily. Eating low-calorie foods
throughout the day will reduce hunger and cause
weight loss.
Disadvantages:
Many medical and nutrition professionals agree
with this plant-based, high-fiber approach.
However, they believe 10% total daily fat intake
is too low. Dietary fat provides essential fatty
acids and the fat soluble vitamins A, D, E, K
needed for normal cell function and tissue growth.
At this fat-consumption level, it is difficult to
consume all essential fatty acids naturally found
in foods. This diet may not be practical for all.
Those eating outside the home on a regular basis
will find it difficult to maintain this low-fat
diet. Low-fat diets often fail to satisfy appetite
and may not be palatable for some people.
Advantages:
Weight loss may occur with this plan. It
encourages eating balanced meals that include
high-fiber fruits, vegetables, beans and grains.
Meals are customized to meet personal needs and
tastes from a wide range of foods and menus.
Although debated in the medical community, there
is evidence low-fat diets play a positive role in
preventing heart disease and some cancers. The
Pritikin diet also encourages daily exercise and
stress-reduction techniques.
A good supplement to take while on this diet
would be dietrine carb blocker. For more

Protein Power Lifeplan
(Michael R. Eades, MD, and
Mary Dan Eades, MD)
The Diet Plan Theory:
The Protein Power Lifeplan diet is a
high-protein, high-fat, low-carbohydrate eating
plan. The diet allows for liberal amounts of fish,
poultry, red meat, low-fat cheese, eggs and tofu.
It offers a three-tiered nutrition plan designed
for your level of health commitment: Hedonist,
Dilettante or Purist. Daily caloric needs are
determined based on protein requirements that are
linked with activity levels. The Eades' Protein
Power Lifeplan is based on the theory that the
body is designed to metabolize and thrive on fats
and proteins; there are no physical needs for
carbohydrates and processed foods. The diet
focuses on controlling insulin levels by
decreasing carbohydrate consumption. By ingesting
a low-carbohydrate diet, the body uses fat for
energy versus burning glucose from carbohydrate
digestion. Using fats for the body's energy source
will decrease appetite and promote weight loss.
Disadvantages:
The Power Protein Lifeplan restricts
carbohydrates and calories, limiting the amount of
essential vitamins and minerals consumed naturally
in foods to maintain health. High-fat diets are
debated in the medical community. However, there
is strong evidence to support increased
cholesterol levels, and increased risk of heart
disease, osteoporosis, cancer and the potential
for accelerating loss of kidney function. There
are no long-term randomized studies to support the
safety of this diet or to support the theory of
the body's preference to metabolize proteins and
fats with greater efficiency than carbohydrates.
Advantages:
Weight loss may occur with this diet. The plan
encourages consuming healthier fats, low-fat
cheese and avoiding fried foods.
Sugar Busters
(H. Leighton and
associates) (H. Leighton and associates)
The Diet Plan Theory:
The Sugar Busters diet is a high-protein,
high-fat, low-carbohydrate plan. This diet
recommends reducing all refined sugars along with
some high-sugar fruits and vegetables. Restricted
foods include refined sugars, potatoes, corn,
white rice, some breads, beets, carrots, corn
syrup, molasses, honey and soda. The authors
believe sugar is toxic. The plan holds that when
refined sugars are eaten, blood sugar rises
quickly and this causes an overabundance of
insulin. The excess amount of insulin is not
readily used to convert blood sugar - glucose -
into energy. Instead, the body stores the glucose
as fat, leading to weight gain. Eliminating
refined sugars forces the body to convert fat into
energy versus burning glucose from carbohydrate
digestion. Appetite subsides, the body stores less
fat and weight loss occurs.
Disadvantages:
The authors' scientific theories are misleading.
Sugar is really not TOXIC. Pesticides are toxic.
They claim lower insulin levels in the blood
stream can reduce insulin resistance. Insulin
resistance is a medical condition diagnosed by a
physician and is typically seen in obese people
and Type 2 diabetics. The authors also believe you
can avert diabetes with this diet. Eating sugar
itself does not cause diabetes or insulin
resistance in a healthy person. But, highly
refined white sugar on its own does make blood
sugar levels rise quicker than eating a complex
sugar (such as a carbohydrate) combined with fat
and protein. Being overweight is a factor in
developing both insulin resistance and diabetes.
Losing weight, with any diet plan, aids in
preventing these conditions. The medical community
continues to debate the effect long-term,
high-protein diets have on accelerating the loss
of kidney function, elevating cholesterol levels,
increasing risk for heart disease, osteoporosis
and cancer. There have been no long-term
randomized studies to support the safety of the
Sugar Busters diet. Following this diet over the
long term will be difficult.
Advantages:
Weight loss may occur with this diet. It provides
clear guidelines on foods to avoid and it
encourages eating high-fiber vegetables,
stone-ground whole grains, lean and trimmed meats,
fish, fruit and drinking alcohol in moderation.
The authors recommend looking at your food
portions versus traditional calorie counting.
A good supplement to take while on this diet
would be herbal phentermine or dietrine patches
which boost your energy on your low carb diet. For
those of you that cheat with the we suggest buying
a bottle of dietrine carb blocker. For more

Suzanne Somers' Get
Skinny on Fabulous Food
(Suzanne Somers and
associates)
The Diet Plan Theory:
Somers' diet is a high-protein, high-fat,
low-carbohydrate eating plan. The diet foods
include unlimited amounts of meat, cheese, eggs,
cream, oils and butter; and controlled portions of
low-carbohydrate vegetables, whole-grain pastas,
cereals, breads, beans, fruits and non-fat dairy
products. There is a list of "funky foods"
to eliminate, guidelines of when to eat fruits,
and how to combine protein, fat, vegetables and
carbohydrates. The diet is based on the theory
that when eating protein and carbohydrates
together, their enzymes cancel each other, halting
digestion and leading to weight gain. The key to "Somersizing"
is to eliminate foods high in sugars, a.k.a.
carbohydrates.
Disadvantages:
There is no scientific data to support combining
certain foods to lose weight or that protein and
carbohydrate enzymes react when eaten together to
stop digestion. Some foods naturally combine
protein and carbohydrates, including nuts, milk,
beans and whole-grain breads. The body digests
these foods. The medical debate over potential
harmful effect of long-term, high-protein diets on
kidney function, cholesterol levels, and increased
risk for heart disease, osteoporosis and cancer
also applies to this plan. Ms. Somers herself had
a bout with breast cancer. Whether this is related
or not is, of course, up for speculation and
discussion. There are no long-term randomized
studies to support the safety of the diet.
Advantages:
Weight loss may occur with this diet. Meals are
customized from a wide range of foods to meet
personal tastes.
A good supplement to take while on this diet
would be dietrine carb blocker. For more

pill review page.
The Zone Diet
(Barry Sears, Ph.D.)
The Diet Plan Theory:
The Zone diet is a high-protein, higher-fat,
lower-carbohydrate eating plan. It is not as
restrictive as other high-protein diets. It allows
for a broad range of foods to be consumed. A small
amount of protein is combined with twice the
amount of "favorable" carbohydrates,
including fruits and vegetables. If choosing "less
desirable" carbohydrates, the portion size is
smaller. Sears' Zone Diet is based on the theory
that the human body is genetically programmed to
reach peak efficiency when all meals, including
snacks, consist of a set caloric ratio of
carbohydrates, proteins and fats. The diet
recommends 40% of calories from carbohydrates, 30%
from protein, and 30% from fats (40-30-30). When
this ratio is achieved, the body is working within
the "zone." The body will have maximum
energy and weight loss.
Disadvantages:
The medical and nutrition community have mixed
feelings about the Zone Diet. There are no
long-term randomized scientific studies to support
the theory the human body is genetically designed
to reach maximum efficiency with a 40-30-30
caloric ratio. The zone diet ultimately is a
low-calorie diet. It is difficult to consume
essential daily vitamins and minerals naturally
from foods on low-calorie diets. Following the
Zone Diet over the long term may be difficult.
Advantages:
Weight loss may occur with this diet. It
encourages eating balanced meals that include
high-fiber fruits, vegetables and beans and
grains. The eating plan is easy to follow.
Summary:
While there are many more diets available, these
are the ones that seem to generate the most
interest and the most questions. We will not even
begin to address fad diets such as the "
cabbage soup diet" or the " Hollywood
diet" etc. There is simply no role for the
use of get-skinny-quick fads. They are
nutritionally devoid, and frankly dangerous.
Conclusion
Maintaining your ideal body weight is a balancing
act between food consumption and calories needed
by the body for energy. You are what you eat. The
kinds and amounts of food you eat affect your
ability to maintain your ideal weight and to lose
weight.
Medical science has established that eating
proper foods can influence health for all age
groups. The U.S. Department of Agriculture's
current dietary guidelines state:
"Eat a variety of foods. Balance the food
you eat with physical activity--maintain or
improve your weight. Choose a diet low in fat,
saturated fat, and cholesterol. Choose a diet
moderate in sugars. Choose a diet moderate in salt
and sodium. If you drink alcoholic beverages, do
so in moderation."
Obesity At A Glance |
 |
Obesity means having excess
body fat. For adults 35 and older, BMI greater
than 27 is considered obese. |
|
|
 |
Obesity is not just a
cosmetic consideration. It is a chronic
medical disease that can lead to diabetes,
high blood pressure, heart disease,
gallstones, and other chronic illnesses. |
|
|
 |
Obesity is difficult to
treat and has a high relapse rate. Greater
than 95% of those who lose weight regain the
weight within 5 years. |
|
|
 |
Even though medications and
diets can help, the treatment of obesity
cannot be a short-term "fix" but has
to be a life-long commitment to proper diet
habits, increased physical activity, and
regular exercise. |
|
|
 |
The goal of treatment should
be to achieve and maintain a "healthier
weight", not necessarily an ideal weight. |
|
|
 |
Even a modest weight loss of
5%- 10% of initial weight and the long-term
maintenance of that weight loss can bring
significant health benefits by lowering blood
pressure and lowering the risks of diabetes
and heart disease. |
|
|
 |
Chances of long-term
successful weight loss are enhanced if the
doctor works with a team of professionals
including dietitians, psychologists, and
exercise professionals. |
|
A good supplement to take while
on the Zone diet would be herbal phentermine or
dietrine patches which boost your energy on your
low carb diet. For more information on these
